A simple captcha for community creation would prevent this
I feel like the little "write why" box that some instances have for account creation would be well fit for this. But for creating communities, or atleast for big instances to keep them from having tons of ghost communities.
If you're explicitly spamming, you'd just put garbage in the 'why' box as well.
Right. Effectively you DOS the site admins this way, making it hard for actual community set up.
But if you combine it with rate limiting, email verification, and a captcha, maybe it can be slowed to a manageable crawl.
